Metacat

Append filter query (fq) to the main query. The fq looks like:
fq=(readPermission:"public")OROR....

The username and group information will be got from the session.

I also tested that if there is a fq in the user specified query, it wouldn't cause any issue:

The user specified query is:
q=title:*solr*&fl=title,id&fq=id:tao.1

And the actually query was executed is:

webapp=null path=/select params={{main(fl=title,id&q=title:*solr*&fq=id:tao.1),extra(fq=(readPermission:"public"))}}
